HEICO is delivering strong double-digit growth across both aerospace aftermarket and electronics, but the stock’s premium multiple leaves limited room for error. The report rates the shares a Hold despite record earnings and cash flow.
Heico Corporation (HEI) combines a high-quality aerospace aftermarket franchise with a growing portfolio of mission-critical electronics. Fiscal 2025 revenue reached $4.49B, operating income reached a record $1.02B, and net income reached a record $690.4M. Momentum continued in fiscal Q2 2026, when revenue rose 25% to $1.38B, diluted EPS increased 48% to $1.66, and operating cash flow rose 43% to $292M.
The investment case rests on three facts: HEICO has developed about 20,000 FAA-approved PMA parts, both operating segments are producing double-digit organic growth, and the company has repeatedly converted growth into cash. The main constraint is valuation. At a reference price of $349.61, HEI trades at 63.3x trailing earnings, 51.3x forward earnings, and 2.7x PEG. That multiple leaves less room for execution mistakes, acquisition missteps, or an aerospace slowdown.
For a moderate-risk investor with a medium-term horizon, the appropriate stance is Hold. The business deserves a premium because of its regulatory barriers, aftermarket exposure, margins, and acquisition record. The stock does not deserve an unlimited premium, particularly with debt rising after four fiscal 2026 acquisitions and the share price near the upper half of its $256.02 to $376.86 52-week range.
Heico Corporation (HEI), founded in 1957 and headquartered in Hollywood, Florida, operates in aerospace, defense, and electronics. The company employs about 11,100 people and reports through two principal segments: the Flight Support Group and the Electronic Technologies Group.
Flight Support Group generated $3.12B of fiscal 2025 revenue, or about 69.5% of the segment total before corporate eliminations. Electronic Technologies Group generated $1.41B, or about 31.5%. FSG sells replacement parts, repair and overhaul services, distribution, avionics, and specialty aerospace and defense products. ETG supplies high-reliability electronics, power systems, RF and microwave products, sensors, interconnection devices, and other components.
HEICO has completed about 107 acquisitions since 1990, giving the company a long record of assembling specialized businesses. The strategy is unusual in that acquisitions sit alongside strong organic growth rather than replacing it. Fiscal Q2 2026 consolidated organic net sales growth was reported at 18%, while the company also benefited from fiscal 2025 and fiscal 2026 acquisitions.
FSG remains the economic engine. In fiscal Q2 2026, FSG revenue rose 21% to $929.4M, operating income increased 31% to $243.1M, and operating margin expanded to 26.2% from 24.1%. Management attributed the performance to double-digit organic growth across product lines, stronger aftermarket replacement-parts volume, favorable mix, and selling, general, and administrative efficiencies.
ETG delivered the faster growth profile. Fiscal Q2 2026 revenue increased 34% to $459.5M, operating income rose 56% to $121.8M, and operating margin reached 26.5% versus 22.8% a year earlier. Demand was broad across electronics, defense, aerospace, and space products. ETG's margin before acquisition-related amortization was 30.6%, although management emphasized that shipping mix can create quarterly volatility.
The more recent fiscal Q3 2026 investor presentation showed the same pattern. FSG revenue increased 18% to $947.8M with a 25.9% operating margin, while ETG revenue increased 36% to $483.5M with a 26.0% operating margin. The nine-month figures were also strong, with consolidated revenue of $3.97B, operating income of $965.5M, and operating margin of 24.3%.

HEICO's flagship product franchise is its FAA-approved replacement-parts platform. The company has developed approximately 20,000 parts with FAA PMA approval and adds roughly 400 to 550 PMAs per year. Each approval expands the catalog, increases customer coverage, and creates another opportunity to replace a higher-priced OEM part.
The franchise covers rotables, repairables, expendables, proprietary repairs, and component exchange services. In the fiscal Q2 2026 discussion, management reported organic growth of about 2% in parts, 21% in specialty products, and 10% in component repair. Specialty products and replacement parts also produced a favorable mix effect on FSG margins.
HEICO's repair model can improve profit even when reported revenue grows more slowly. Management said greater use of DER and PMA-friendly repairs allows the company to use its own products instead of expensive OEM parts, creating lower top-line growth but higher bottom-line growth. That is a useful distinction for investors focused only on sales momentum.
The strongest competitive barrier in FSG is the combination of FAA qualification, engineering expertise, customer trust, and a large installed product catalog. HEICO's 2025 FSG research and development spending was $43.7M, up from $36.7M in fiscal 2024 and $26.4M in fiscal 2023. That investment supports new PMAs, proprietary repairs, and product redesign.
ETG adds a second moat through mission-critical performance. Three HEICO subsidiaries, 3D PLUS, Exxelia, and VPT, supplied electronic components for NASA's Artemis II mission. HEICO also acquired 90% of Southwest Antennas in fiscal 2026, adding rugged antennas for ground-based defense and law enforcement applications.
HEICO's operating model benefits from high throughput and strong fixed-cost absorption. In fiscal Q2 2026, FSG's operating margin increased by 210 basis points year over year, while ETG's margin increased by 370 basis points. Management linked both improvements to volume, product mix, and selling, general, and administrative efficiencies.
The main operational pressure is component availability. Management said repair stations carried massive backlogs and that some component repair work was waiting for supplier parts. The issue is improving, but it restrained component repair growth, which management estimated at about 10% organically in Q2.
A customer-requested pull-forward of defense-related sales improved FSG's Q2 operating margin by about 60 basis points. That benefit strengthens the reported quarter but also means some sales shifted from the second half of fiscal 2026. The broader operating evidence remains positive because FSG and ETG both delivered strong organic growth across multiple product categories.
HEICO's commercial aerospace exposure is tied to fleet utilization, aircraft age, maintenance cycles, and the supply of replacement parts. IATA reported full-year 2025 passenger demand growth of 5.3%. Airbus projects passenger traffic growth of 3.6% annually through 2044, while Boeing estimates the aviation support and services market at $4.9T over 2026 to 2045.
Those figures support a durable aftermarket opportunity rather than a narrow new-aircraft production thesis. Maintenance backlogs, labor shortages, and OEM delivery constraints increase the value of suppliers that can provide approved parts and repairs with short lead times. HEICO's Q2 comment that customers were pushing the company for more parts fits that market structure.
Defense and space provide a second demand channel. About 31% of fiscal 2025 sales came from defense, satellite and spacecraft components, and homeland security products. The fiscal 2026 U.S. defense request included $362B for operations and maintenance plus $23B for facility sustainment, restoration, modernization, and depot maintenance. That spending mix is relevant to HEICO because FSG supplies sustainment products while ETG supplies electronics used in defense and space systems.

FSG serves commercial airlines, air cargo carriers, repair and overhaul facilities, OEMs, asset-management companies, and U.S. and foreign governments. ETG sells to defense primes, government laboratories, satellite and spacecraft manufacturers, medical equipment producers, telecommunications companies, and industrial customers.
Customer decisions center on certification, reliability, price, lead time, and the ability to keep an aircraft or mission system operating. HEICO's PMA catalog and FAA-approved repair capability address certification requirements, while its 10-K identifies competitive pricing, short lead times, and customer relationships as key advantages.
The customer mix also provides some diversification inside aerospace. Commercial aviation represented 58% of fiscal 2025 sales, defense and space represented 31%, and other industrial markets represented 11%. Management described the Middle East as a relatively small portion of total sales, while reporting strength across broader commercial and defense demand.
FSG competes with major engine and component OEMs, airline-owned maintenance operations, and independent MRO and parts suppliers. AAR Corp. (AIR) and VSE Corp. (VSEC) are relevant aftermarket and distribution comparisons. TransDigm Group (TDG) is a closer comparison for proprietary aerospace components and aftermarket economics, although its portfolio and pricing model differ from HEICO's.
ETG competes with broader aerospace and defense electronics companies such as RTX (RTX), Honeywell (HON), Moog (MOG.A), Woodward (WWD), Eaton (ETN), Crane Company (CR), and Parker-Hannifin (PH). These companies generally have broader system exposure, while HEICO emphasizes smaller, specialized components. That niche focus helps explain how HEICO can produce a 25.5% consolidated operating margin in fiscal Q2 2026.
HEICO's advantage is not simply low cost. Its roughly 20,000 PMA parts, annual approval cadence, repair expertise, and acquisition platform create a combination that smaller competitors may struggle to match. OEMs retain scale and installed-base influence, so HEICO's competitive position depends on continuing to add approvals, maintain quality, and preserve customer trust.
The macro backdrop is favorable for HEICO's two largest end markets. Passenger demand increased 5.3% in 2025, the Boeing support market forecast totals $4.9T through 2045, and U.S. defense spending includes substantial operations, maintenance, and depot funding. These facts support commercial aftermarket and defense sustainment demand.
Geopolitical risk has both positive and negative effects. Management said the conflict involving Iran affected some Middle East sales, but the region represents a relatively small portion of total revenue. Management also reported strong defense orders, record or near-record backlogs in several markets, and a multiyear defense tail from replenishment and higher allied spending.
The principal external risks are supplier disruption, tariffs, export controls, embargoes, cybersecurity incidents, and changes in government procurement. HEICO's 10-K specifically identifies those risks. Its defense and space exposure supports demand, but it also increases the importance of regulatory compliance and international trade rules.
Debt has risen after four fiscal 2026 acquisitions, even as HEICO keeps generating strong operating cash flow and maintains a premium-quality balance sheet profile.

Get Full Access →HEICO is one of the stronger compounders in aerospace and defense, supported by a rare combination of regulatory approvals, aftermarket demand, high margins, and acquisition discipline. Fiscal 2025 and fiscal 2026 results show that the model is producing both earnings growth and cash flow, while NASA Artemis II supplier roles and the Southwest Antennas acquisition extend the company's reach into mission-critical electronics.
The stock is a different proposition from the business. At $349.61, HEI already commands a premium multiple, and debt has risen as management funds acquisitions. The $390 fair value estimate supports a Hold rather than a fresh aggressive entry. A decline toward $340 would improve the risk-reward balance, while prices above $420 would demand a level of growth and execution that the current evidence does not justify.
Institutional ownership of 81.2%, insider ownership of 22.8%, and a short position equal to 1.4% of the float show a shareholder base already heavily invested in the HEICO story. That sponsorship can support the stock when operating results remain strong, but it also makes valuation discipline important. The durable business earns a place on a medium-term watchlist; the price determines whether it earns new capital.
